Privacy Policy

VisualTextbook (“VisualTextbook”, “we”, “us” or “our”) operates the website available at https://visualtextbook.com and related pages and services (collectively, the “Platform”).

This Privacy Policy explains what information we collect, why we collect it, how we use and protect it, and the choices available to you.

By accessing or using VisualTextbook, you acknowledge that you have read this Privacy Policy.

1. Information We Collect

Most educational content on VisualTextbook can be viewed without creating an account or directly providing personal information.

Depending on how you use the Platform, we may collect the following categories of information.

Information you provide to us

If you contact us through our contact form or by email, we may receive information such as:

• your name;
• your email address;
• the contents of your message or enquiry; and
• any other information you voluntarily provide.

Please do not submit sensitive personal information through the contact form unless it is necessary for your enquiry.

Administrative users may also provide authentication information required to access restricted administrative functions.

2. Technical Information

When you visit VisualTextbook, certain technical information may be processed automatically by our website, hosting infrastructure or security systems, including:

• IP address;
• browser type and version;
• device type;
• operating system;
• requested pages or URLs;
• date and time of requests;
• referring page;
• basic network and diagnostic information; and
• security or abuse-prevention information.

We may use this information to operate the website, diagnose technical problems, prevent abuse, maintain security and understand general website performance.

3. Local Storage and Similar Technologies

VisualTextbook may use browser storage technologies such as localStorage to provide features including lesson progress, bookmarks, interface preferences or similar functionality.

Information stored locally in your browser generally remains on your device unless you clear your browser data.

We may also use cookies or similar technologies where they are necessary for website functionality, security or services that we introduce in the future.

VisualTextbook does not currently sell personal information or use personal information for third-party targeted advertising.

If we introduce additional analytics, advertising or tracking technologies in the future, this Privacy Policy will be updated accordingly.

4. How We Use Information

We may use information collected through VisualTextbook to:

• provide and operate the Platform;
• display educational content and interactive learning features;
• respond to questions, feedback and support requests;
• maintain, debug and improve the Platform;
• prevent spam, fraud, abuse and security incidents;
• monitor website reliability and performance;
• protect our users, systems and legal rights;
• comply with applicable laws or lawful requests; and
• maintain administrative access to the Platform.

We will not use personal information for purposes that are materially unrelated to those described here without an appropriate legal basis or notice where required.

5. Contact Form Information

When you submit the contact form, the information you provide may be processed by our email delivery provider so that your message can be delivered to us.

We may also process limited technical information associated with contact submissions for spam prevention, abuse detection and rate limiting.

Contact messages are used primarily to respond to your request, investigate problems, receive feedback or otherwise communicate with you about your enquiry.

6. Service Providers

We rely on third-party service providers to operate VisualTextbook.

These may include:

• Supabase for database, authentication and related infrastructure;
• Resend for delivery of contact-form emails;
• hosting, content-delivery and infrastructure providers;
• security and monitoring services; and
• Google Fonts or similar providers used to deliver website fonts and assets.

These providers may process limited information as necessary to provide their services to us.

Their handling of information is also governed by their respective privacy policies and contractual terms.

7. International Processing

Some of our service providers may operate infrastructure in countries outside India.

As a result, information may be processed or stored outside your state or country depending on the infrastructure used by those providers.

Where required by applicable law, we will take appropriate measures concerning such processing or transfers.

8. Data Retention

We retain personal information only for as long as reasonably necessary for the purpose for which it was collected, including to:

• respond to enquiries;
• maintain security;
• resolve disputes;
• comply with legal obligations; and
• establish or defend legal claims.

Technical logs may be retained for limited periods for security, diagnostics and operational purposes.

Information stored in your browser through localStorage remains under your control and may generally be removed by clearing your browser's site data.

9. Children and Students

VisualTextbook provides educational content that may be used by school students, including users under the age of 18.

Most learning material can be accessed without providing personal information.

We encourage children to use the Platform with the knowledge and supervision of a parent, guardian or teacher where appropriate.

Users under 18 should avoid providing unnecessary personal information through contact forms or other communication channels. Where consent of a parent or lawful guardian is required under applicable law, such consent should be obtained before providing personal information.

If you are a parent or guardian and believe a child has provided personal information to us inappropriately, please contact us so that we can review and, where appropriate, delete the information.

10. Security

We use reasonable technical and organisational measures designed to protect the Platform and information processed through it.

These measures may include authentication controls, database access controls, encryption in transit, security headers, input validation, rate limiting and other application-security measures.

However, no website, database or method of electronic transmission can be guaranteed to be completely secure.

Users should also take reasonable precautions when communicating information online.

11. Sharing of Information

We do not sell or rent your personal information.

We may share information only where reasonably necessary with:

• service providers operating on our behalf;
• professional advisers where necessary;
• law-enforcement, regulatory or governmental authorities when required by applicable law or valid legal process;
• persons involved in detecting or preventing fraud, abuse or security incidents; or
• a successor organisation in connection with a merger, restructuring, acquisition or transfer of all or part of our business or assets.

Service providers are permitted to process information only as necessary for the services they provide to us, subject to applicable arrangements and law.

12. Your Rights and Choices

Depending on applicable law and the circumstances, you may have rights relating to your personal information, including the ability to:

• request information about personal data we hold about you;
• request correction of inaccurate information;
• request deletion of information where applicable;
• withdraw consent where processing is based on consent;

We do not control those services and are not responsible for their privacy practices, content or security.

You should review the privacy policies of any third-party services you choose to use.
